GLONASS and GPS performance evaluation in IAC is implemented through regular service mode based on the measurements from the global network of stations by self-designed software tools. It provides for regular software update featuring the most advanced processing models and techniques. Many of estimations are obtained using the master data, calculated using "AKVAPAS" software package registered in the State Register under № 46393-11 and authorized for use in the Russian Federation (the certificate of approval for measuring tool type RU.E.27.018. № 42 157).
The estimations results updated within intervals from 5 minutes to 1 day are available on a special IAC technological web-site. The site is mostly aimed at advanced users qualified in analysis of satellite navigation systems’ performance. Data collection and processing are carried out in automatic mode with occasional operator control due to large amount of data obtained. IAC technological web-site contains the following information:
Every section has its own "Description" tab which contains description of the data provided as well as the calculation techniques. An access to the IAC technological web-site is granted upon preregistration.
